(PHYS.ORG) — Security weaknesses on many popular fitness trackers may allow hackers to access or potentially manipulate user data, a study showed Monday.
The study of seven Android-powered trackers by the security firm AV-Test showed vulnerabilities similar to that found in its research from a year earlier—with many devices lacking secure connections or tamper protection.
The researchers said the Apple Watch, which was evaluated using different criteria because of its operating system, had a “high security rating” despite some “theoretical vulnerabilities.”
